| EBV class |
Genetic composition |
| EBV name |
Effective population size of top predators |
| Step in identification process |
Temporal changes in allele frequencies? Sequential MR? Linkage disequilibrium? Genomic SNPs? |
| Definition |
Size of an ideal population that loses genetic variation at the same rate as the focal population (https: //onlinelibrary .wiley. com/doi/full/1 0.1111/brv. 12852) |
| Metric |
Either 1) a genetic estimate of contemporary effective population size (Ne) or 2) a proxy estimate of effective population size based on census population size (Nc) (e. g. for many species can assume Ne = Nc x 0.1) |
| Spatial resolution unit |
Estimated for each population of each focal species |
| Temporal resolution unit |
(Should reflect generation time of focal species to detect meaningful change ?) |
| Taxonomic/ ecosystem focus group |
Marine mammals, Marine birds, Predatory marine fish (?), Predatory invertebrates (?), Cephalopods |
